<hierarchicaldatatemplate x:key="NodeTemplate">
<textblock x:name="tb">


<hierarchicaldatatemplate.itemssource>
<binding xpath="child::node()">

<hierarchicaldatatemplate.triggers>
<datatrigger binding="{Binding Path=NodeType}" value="Text">
<setter targetname="tb" property="Text" value="{Binding Path=Value}">

<datatrigger binding="{Binding Path=NodeType}" value="Element">
<setter targetname="tb" property="Text" value="{Binding Path=Name}">

<dockpanel grid.row="1">

You need to add a data template with a textbox in it as shown below :

C#

<TreeView x:Name="MyTreeView">
           <TreeView.Resources>
               <DataTemplate x:Key="NormalTemplate">
                   <StackPanel Orientation="Horizontal">
                       <TextBlock Text="{Binding ID}" Margin="3"/>
                       <TextBlock Text="-" Margin="3"/>
                       <TextBlock Text="{Binding Name}" Margin="3"/>
                   </StackPanel>
               </DataTemplate>
               <DataTemplate x:Key="EditTemplate">
                   <TextBox Text="{Binding Name}"/>
               </DataTemplate>
           </TreeView.Resources>
           <TreeView.ItemTemplate>
               <HierarchicalDataTemplate
                            ItemsSource="{Binding Team}">
                   <ContentPresenter Content="{Binding}">
                       <ContentPresenter.Style>
                           <Style TargetType="{x:Type ContentPresenter}">
                               <Setter Property="ContentTemplate"
                                       Value="{StaticResource
                                               NormalTemplate}"/>
                               <Style.Triggers>
                                   <DataTrigger
                                        Binding="{Binding IsSelected,
                                        RelativeSource={RelativeSource
                                             FindAncestor,
                                        AncestorType={x:Type TreeViewItem}}}"
                                             Value="True">
                                       <Setter Property="ContentTemplate"
                                               Value="{StaticResource
                                                       EditTemplate}" />
                                   </DataTrigger>
                               </Style.Triggers>
                           </Style>
                       </ContentPresenter.Style>
                   </ContentPresenter>
               </HierarchicalDataTemplate>
           </TreeView.ItemTemplate>
       </TreeView>
